A walker was airlifted from a Snowdonia mountain for the second time in eight days.

Ogwen Valley Mountain Rescue Organisation was called out on Thursday afternoon after a passing walker came across a woman lying unconscious against a wall on Tryfan.

The rescuers made their way to the site at the South Col, about 200m from the main summit after being alerted at 3.35pm.

On arriving at the scene, the team realised it was the same woman who had been found by a passing group in a similar condition eight days earlier on the mountain.

On that occasion, a Sea King helicopter from RAF Valley flew to the summit of the 917m (3,009ft) mountain and airlifted the woman to Ysbyty Gwynedd for assessment.

On Thursday, cloud cover prevented the RAF crew reaching the site, so Ogwen Valley Mountain Rescue Organisation members stretchered the woman to below the cloud base and a Sea King again flew her to hospital.
